APPARATUSFOR PURIFYING LIQUIDS.

To all whom it may concern:

Be it known that I, Lnvrs MILLER BOOTH, a citizen of the United States,and a resident. of Plainfield, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in Apparatusfor Purifying Liquids, of which the followtion of the cylindrical tankshall form a capacious settling chamber of large cross sectional area sothat the upward flow of the liquid throughthe settling chamber may be asslow as possible in order to permit the fine precipitate to settlerather than to be carried upward by the upward flow of the liquid.

In the accompanying drawing, Figure 1 is aplan view of my apparatus;Fig. 2 is an elevation part y in section of my apparatus; and Fig. 3 isa partial sectional View on the line y-y of Fig. 1.

Similar numerals refer to similar parts throughout the accompanyingdrawing.

It will be understood that many'changes may be made in the apparatuswithout departing from the spirit or scope of my in vention.

The apparatus shown in the drawing is particularly adapted to thetreatment of water, and consists of a cylindrical tank 1, the lowerportion of which forms the settling chamber 2. In the upper portion ofthis tank is the softening or mixing chamber 3 provided with theagitators 4, and a conduit or pipe 5 of such dimensions and capacitythat the treated liquid will be dis charged from the softening chamberinto the settling chamber near the bottom thereof at a rate of flowwhich will not cause undue agitation of the liquid in the settlingchamber. Near the upper end of the settling chamber, I have provided afilter 6, through which the purified water passes into the storagechamber 7, which is provided with a discharge outlet 8. By thisconstruction practically the entire area of the lower portion of thetank 1 is available to provide a large and capacious settling tank oflarge cross sectional area, and, therefore, the up Specification ofLetters Patent.

ward flow of water through the settling tank is as slow as possible in atank of a given diameter, thus permitting the fine precipitate tosettlerather than be carried upward by the upward flow of the water, andthe dimensions of the filter, while adequate for the purpose, arereduced to a minimum. I find in practice that with'the apparatusconstructed as shown and described the quantity of water which can besuccessfully treated is greater in a given time than with a cylindricalltank apparatus of the style heretofore in use, as the capacity of thepurifying apparatus is dependent upon the cross-sectional area of thesettling tank, which determines the rate of upward flow of the watertherethrough, whichmust be at of the fine particles of precipitatesuspended in water.

From the foregoing description, it will be apparent that the presentinvention involves the novel feature of providing a reaction compartmentwithin the main tank, so that one wall of the latter forms a wall of thetank, while the opposite wall designated as 45* cooperates with thecylinder wall to provide a segmental compartment 3 which is located nearthe upper end of the main tank. This locatlon and arrangement of thereaction compartment thus provides a capacious and unobstructed settlingspace at the bottom ofthe main tank which is of large cross sectionalarea and into which leads the conduit 5 from the reaction compartment.This conduit has its discharge end close to the bottom of the settlingspace 2, so that the softened water and insoluble particles issuing fromthe reaction compartment 3 will be fed into the settling space in asubstantially inert condition, to thus provide for the effectiveseparation by gravity of the heavy insoluble particles and collection ofsludge while the lighter liquid rises to the top of the tank and passesout through the wood filter '6.

The balance of the apparatus is too well known to need furtherdescription.

Having described my invention, what I claim as new and desire to secureby Letters Patent is:

1. An apparatus for purifying liquids comprising a cylindrical tank, asegmental reaction compartment formed entirely within said cylindricaltank at the upper end thereof, a settling space of relatively largecross sectional area, formed by a slower speed 7 the lower portion ofsaid cylindrical tank,

and a conduit of lesser cross sectional area than said segmentalreaction compartment for conveying the liquid therefrom to a point nearthe bottom of the settling space.

2. An apparatus for purifying liquids comprising a cylindrical tank, areaction or mixing compartment consisting of a section of the upperportion of said cylindrical tank, the cylindrical Wall of saidcylindrical tank forming one of the Walls of said reaction or mixingcompartment, a settling'compartment consisting of the lower portion ofSigned at l'l"ew: Yorkcity; in: the county 20 of New York and StateofiNew York this 15th 'lay' of J 1118, A; D.- 1914..
